Answer: The correct answer for the blank is-

Prophase.

M phase (mitotic phase) is the second phase of cell cycle (the first being interphase, which contains G1, S, and G2 stages).

In the M phase, the parent cell is divided into two daughter cell (through a sequence of 5 stages in the order- Prophase, metaphase, anaphase, telophase, and cytokinesis). The daughter cells have same number of chromosomes as that of the parent cell.

Prophase marks the beginning of M phase. In this phase, nuclear envelope is broken down and chromatin becomes condensed into visible chromosomes. Mitotic spindle formation is also initiated in this phase.

Thus, prophase is the right answer.

Thus plants need nitrogen-fixing bacteria to convert atmospheric nitrogen into ammonium, which is available for plants to absorb it. </span>
